GAS-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 731,997, dated June 23,1903.

Application led April 11, 1903. Serial No. 152,120. (No model.)

T0 all whom, t may concern,.-

Be it known that I, ALLAN M. FISHER, a citi- Zen of the United States ofAmerica, residing atEast Liverpool, in the county of Columbiana andState of Ohio, have invented certain new and useful Improvements inGas-Regulators, of which the following is a specification, referencebeing had therein to the accompanying drawing.

This invention relates to certain new and useful improvements ingas-regulators, and relates more particularly to that class ofregulators which are used to maintain a predetermined pressure in theoutlet-pipe, the pressure of the supply to which is variable.

The object of this invention is to provide a cheap and eiiicientregulator which may be interposed within the pipe, whereby anypredetermined pressure may be had in the outlet-pipe, the pressure ofthe supplyof which is variable.

In describing the invention in detail reference is had to theaccompanying drawing, forming a part ot' this specification, and inwhich the view shows a vertical view, partly in section, of my improveddevice.

In the accompanying drawing the reference-numeral 1 indicates a suitablecock for controlling the supply of gas in the outletpipe 2, thesupply-pipe (not shown) of which is connected with a port 3 of thevalve. Interposed in the outlet-pipe 2 at a point adjacent to said cock1 is a T 4, to which is secured the .vertical regulator supply-pipe 5.This supply-pipe has secured to its lower end adjacent the T4 a conicalbracket 6, which supports the outer shell 7 ot' the water-sealedgasometer, the inner valve 8 of which is provided with a suitableguide-tube 9, the lower end of which is supported by brackets 10 10, andthe upper end of which has provided therein apertures 11 11 for thepurpose of permitting the gas which is supplied to the same through pipe5 to escape to the upper end of the inner bell S. A vertical support 12,on the upper end of which a bracket 13 is secured, within which thehorizontal rod 14 is fulcrumed, is provided. The inner bell 8 of thegasometer is provided at its upper end with a` split bracket 15, whichstraddles the said lever 14, and a pin running through said in the lever14. The outer end of this le'ver 14 is provided with a series of notches17 17, in which the support 18 of the weight 19 rests. The movement ofsaid weight 19 determines the pressure at which the gas in theoutletpipe is to be maintained. The opposite end of' this lever hasprovided therein a slot 20, through which the pin 21, provided in thevalve-'stem 22, which encircles the end of said lever, is placed, saidvalve-stem 22 passing through a stung-box 23 in the cock 1 andconnecting with the valve 24 within said cock.

While the gasometer is shown in its dry condition, it is obvious that awater seal may be placed in the same when the device is in operation.

The operation of the device is as follows: The gas passing through theport 3 into the cock 1 from thesupply-main will pass through pipe 2, anda portion of the same will pass through pipe 5 and apertures 11 into theupper end of the inner shell'of the gasometer, when the water withinsaid shell will be forced downwardly, and the water contained in theannular space between said shell and the shell 7 will be forcedupwardly. Should this pressure be sufficient to elevate the weight 19,the end of the lever 14 to which the valvestem 22 is secured will beforced downwardly, thereby forcing the valve 24 against its seat anddiscontinuing the supply of gas. The gas being drawn off from pipe 2 forthe purpose of using the same will decrease the amount contained Withinthe inner shell of said gasometer until such time as the pressure ofsaid gas is insuicient to support the weight 19, when the said weightwill force the inner shell downwardly, thereby elevating stem 22, whenthe valve 24 will again be withdrawn from its seat and more gas bepermitted to enter from the main. This operation being repeated willmaintain the pressure within the outlet-pipe 2, said pressure beingcoincident with the adjustment ot' the weight 19 on the lever 14.

While I have herein shown and described bracket 15 passes through theslot 16, formed a practical form of my invention, yet` it will l Havingfully described my invention, what said cock, the inner shell of saidgasometer being provided at its upper outside end with a bracket whichis 'slidably connected with a lever which is also slidably connectedwith the stem of the cock, the fulcrum of said lever being intermediateof the connection with said bracket and said stem, the free end f saidlever being provided -with an adjustable weight whereby the pressure ofgas necessary to actuate the inner shell of said gasometer may bevaried, thereby regulating the pressure which will actuate said levrrand stem to operate the cock interposed between the supply and outletpipes, substantially as described.

2. In a gas-regulator, the combination of a cock interposed between thesupply and' outlet pipes, said outlet-pipe having a pipe connecting witha gasometer interposed Itherein at a point adjacent to said cock, saidpipe ,connecting with the gasometer extending to the upper end of theguide provided on the inner side of the inner shell of said gasometer,suitable ports provided. in the upper end of said guides t0 permit thegas to pass into.

the upper end of the inner shell of said gasometer, a suitable conicalsupport at the lower end of said pipe connecting with the gasometer. forsupporting the outer shell of the gasometer, the upper end of the innershell of said gasometer being provided witha bracket which is slidablyconnected with the lever which is also slidably connected with the stemof the valve interposed between the supply and outlet pipes, the fulcrumfor said lever being located intermediate of said stem and bracket, andan adjustable Weight provided on the end of said lever opposite fromthat to which the stem is connected whereby the gas-pressure within saidgasometer necessary to actuate said valVe-stem,thereby controlling thesu pply of gas, may bevaried, substantially as described.

In testimony whereof I affix my signature in the presence of twowitnesses.

ALLAN M. FISHER.
